Possible Causes

Loose ribbon cable between UI and main control, Failed user interface board, Oxidized or corroded connectors at display

How to Fix / Troubleshooting

Safety first: Disconnect power before removing the control panel or display bezel.

Steps:

  • Access UI board: On many Viking models, the display and buttons are in the upper control panel or door. Remove the trim screws and gently pull the panel forward.
  • Check ribbon cable: Inspect the flat ribbon or harness between the UI and main control. Reseat both ends, ensuring they are fully inserted and locked.
  • Inspect for moisture: Look for signs of condensation or liquid intrusion around the display. Dry the area thoroughly if needed.
  • Visual board check: Examine the UI board for burn marks, cracked solder joints, or corrosion.

Corrective action: If reseating cables does not clear the error after a power reset, replace the user interface / display board with the correct Viking part number. Handle the new board by the edges to avoid static damage.
